4. PC/Teaching Pendant Connection Method in Multi-axis
Configurations
This section explains the method to permanently connect a PC/teaching pendant in configurations consisting of
multiple axes, so that the PC/teaching pendant connector need not be removed/inserted each time.
The connector is connected to a SIO converter, and the SIO converter sends/receives data to/from each
controller via RS485 serial communication.
The basic specifications are as follow:
[1] Maximum number of connected axes: 16
[2] Maximum length of serial communication cable: 100 m or less
[3] Terminal
resistor: 220
 (Be sure to install a terminal resistor for the last axis to prevent the effect of
radiating noise.)
4.1 Connection Example
Caution: Do not connect the teaching pendant and PC at the same time.
If both are connected at the same time, a communication error (message level) will occur.
